Sienna Miller and her fiancé, Tom Sturridge, have been signed for a new Burberry campaign, a source tells Page Six. The pair joins the ranks of the brand’s current and former faces Cara Delevingne, Emma Watson, Kate Moss and Romeo Beckham. Speculation was that Bradley Cooper’s gal pal, model Suki Waterhouse, may be another new Burberry face. Reps for the English line chose not to comment. Sources said they usually announce their autumn/winter ad talent lineups in July.
